Buying Guide
What sign size and tube diameter should guide my choice?
Sign size and tube diameter determine voltage and current needs. Larger or multiple glass neon tubes typically require higher voltage (7kV–10kV) and higher current (20–30mA). Smaller signs with thinner tubes can work well with lower voltage units (3kV–6.5kV) to preserve brightness while reducing load on the transformer.
How important is the power factor and EMI rating?
A higher power factor and low electromagnetic interference (EMI) help ensure stable brightness and reduce electrical noise in the surrounding area. Units advertising PF above 0.9 and EMI-conscious design are preferable for indoor environments near other electronics.
What safety features should I look for?
Look for protections such as short-circuit, overheat, open-circuit, earth-leakage protection, and grounding compatibility. Grounding features and protective enclosures reduce shock risk in high-voltage installations and improve reliability over time.
Do I need multiple transformers for large installations?
For large signs with many tubes or long runs, using multiple transformers may provide more uniform brightness and easier wiring. Plan tube counts and wiring layouts to balance voltage across tubes and avoid shadows or dim sections.
Are UL-listed or equivalent certifications necessary?
UL-listed transformers or equivalent certifications indicate adherence to safety standards and can simplify installation in commercial spaces. If UL listing is important, prioritize models explicitly marked as UL Listed or with recognized safety certifications.
What installation considerations matter?
Ensure proper mounting, safe clearance from flammable materials, and protected wiring paths. Use appropriate connectors, strain relief, and secure cable management to prevent damage from vibration or accidental tugging on cords.
